Florid cemento-osseous dysplasia : report of 2 cases

2018

Introduction Florid cemento-osseous dysplasia is a non-neoplastic fibro-osseous lesion which often has an asymptomatic slow growth. Unfortunately, these lesions are usually diagnosed through routine radiographic examination. The aim of this study was to describe the main clinical, radiological and histological characteristics of two case reports diagnosed with florid cemento-osseous dysplasia. Case reports Two cases of florid cemento-osseous dysplasia with different clinical and radiological features were presented. Panoramic radiographs showed multiple radiopacities compatible with fibro-osseous lesions in distinct areas of the maxillary bones. The histological study revealed a sclerotic m…

Total Elbow Replacement as Primary Treatment for Complex Fractures of the Distal Osteopenic Humerus

2003

Background: The use of hip and shoulder arthroplasty in elderly patients for grossly displaced intraarticular fractures is becoming more and more accepted. Total elbow replacement (TER) has not been considered an option for the treatment of extensively comminuted fractures of the distal humerus because surgeons feel the outcome is generally not predictable after TER. Evaluation of TER: On the basis of a MEDLINE literature search of this issue and the documented results based on the improvement of implant designs, operative technique and patient selection, TER has a definite role in the treatment of some fractures of the distal humerus.

Is time to joint replacement a valid outcome measure in clinical trials of drugs for osteoarthritis?

2003

The rate of radiographic joint space narrowing is commonly used today as a structural outcome measure in clinical trials evaluating potential disease-modifying drugs in patients with hip osteoarthritis, but this results in a continuous variable. Among the methods proposed to circumvent this problem, it has been suggested that the incidence of total hip arthoplasty (THA) provides a hard outcome measure. It is a dichotomized variable, easy to measure and sensitive to change, with acceptable intrinsic validity. However, because this measure is limited by the variability of factors underlying the decision to perform surgery and the length of waiting lists, it has been suggested that time to ful…

Anterior dislocation in a total knee arthroplasty: A case report and literature review.

2015

Dislocations of a total knee arthroplasty (TKA) are an uncommon injury and only few cases of anterior dislocations have been reported. We report a rare case of anterior dislocation of a 10-year-old posterior stabilized total knee arthroplasty in a 74-year-old woman. The patient was successfully treated by close reduction of the dislocation followed by immobilization in full extension with a long leg cast. Because of a high risk of neurovascular complications, a high index of suspicion for vascular injury must be maintained. For this reason, a proper diagnosis is required and immediate reduction is recommended.

The effect of cement fixation on initial micromotion of the femoral component in condylar knee replacement

1992

Four fresh, cadaveric specimens were fitted with total knee replacements and mounted on a knee joint loading and measuring rig. Femoral component micromotion in the sagittal plane was measured with a transducer during flexion and extension of the specimen. Various condylar designs were used without and with cement. Movement followed a characteristic curve pattern and was less with cement fixation particularly for bone of low trabecular strength as determined by bone sample tests for stiffness. Cement fixation appears to be superior to cementless fixation.

Comparison of Postoperative Coronal Leg Alignment in Customized Individually Made and Conventional Total Knee Arthroplasty

2021

Neutral coronal leg alignment is known to be important for postoperative outcome in total knee arthroplasty (TKA). Customized individually made implants (CIM) instrumented with patient-specific cutting guides are an innovation aiming to increase the precision and reliability of implant positioning and reconstruction of leg alignment. We aimed to compare reconstruction of the hip–knee–ankle angle (HKA) of the novel CIM system iTotal™ CR G2 (ConforMIS Inc.) to a matched cohort of the off-the-shelf (OTS) knee replacement system Vanguard™ CR (Zimmer Biomet). Retrospective analysis of postoperative coronal full-leg weight-bearing radiographs of 562 TKA (283 CIM TKA, 279 OTS TKA) was conducted. V…

Three-year mortality after acute myocardial infarction in patients with different diabetic status

2021

Introduction: The prevalence of diabetes mellitus (DM) in patients with myocardial infarction (MI) is estimated at about 25%. Short and long-term prognoses are worse in DM and hyperglycemia compared with non-diabetics. Objectives: Our aim was to analyze the impact of DM and transient hyperglycemia on in-hospital complications and long-term outcomes in MI patients. Patients and Methods: We evaluated a prospective cohort of 58,394 MI patients in the Polish Registry of Acute Coronary Syndrome in terms of in-hospital complications and 30-day, 12-month, and 36-month outcomes between 2009–2012. Results: Type 1 and 2 DM patients underwent invasive diagnostic and therapeutic procedures less frequen…

Perceived goal setting practices across a competitive season

2019

Goal setting is an effective and frequently used tool for performance enhancement in sports. However, in the previous studies, the focus has been on goal effectiveness among individual male athletes and at one point in time. Therefore, the purpose of this longitudinal study was to examine goal setting practices in women’s sport teams across a competitive season from players’ individual and team perspectives. A total of 146 female players representing 24 teams in ice hockey, ringette, or floorball completed three online surveys. Surveys focused on setting outcome, process, and performance goals, as well as evaluating the follow-through of setting goals and actually reaching these goals acro…
